IAG Performance Air Oil Separator AOS For 2022-24 WRX - Black

The IAG Air / Oil Separator (AOS) is a smart move to protect your Subaru's engine. Developed over years of extensive testing on a range of standard and competitive applications, the IAG AOS offers unparalleled protection for your 2022-2025 WRX FA24F 2.4L engine. Our exclusive AOS design incorporates a 1-liter cast aluminum swirl pot canister that significantly improves oil separation from the PCV system before returning PCV gasses to the intake. Crafted from a lightweight yet durable aluminum housing, the IAG AOS provides enhanced ventilation and features an innovative baffle design that sets it apart from the competition. This AOS works with all fuel types, improves crankcase ventilation, and incorporates our innovative baffle design that sets it apart from competitors' products. Unlike ordinary catch-can systems, the IAG Air / Oil Separator functions without the need for routine draining or maintenance. The oil separated by the AOS gathers along the canister walls, gradually draining into the engine's crankcase. The spacious design of the IAG AOS prevents overflow by facilitating slow drainage, whereas smaller catch cans may struggle to keep pace and often need manual draining. Our exclusive heating system ensures that the collected oil stays clear of sludge, minimizing the risk of reintroducing it into the engine.
